- Another "Not quite ready for Prime Time" release of soft machine porn. Even though this is only a "Rustoleum Rebuild", it demonstrates the tedious tasks involved in getting a machine serviceable after years of neglect. This is only reassembly of the column! Part 2 will hopefully complete the saddle, table, spindle and electrical. Well, it might be three parts...
Nice work. Thats the same spindle adaptor as my Boyer Schultz 6-12
Thanks for that information. I suspect this is a widely used adapter style. I like your shop too. Look forward to your projects.
Thank you. Knowing that pointed to several possible sources. Looks like I have a reasonable part number now.
there's 2 common adapter sizes on 6x12s and yours looks like the smaller one also on tool cutter grinders by the relief in the middle of the taper
Thank you, that's helpful to know.
I have found that the Rustolium smoke grey is a better match for my Clausing restorations?
Your probably absolutely correct. But my Clausing had three different color layers on it, none of which bore any resemblance to the original. I like this machine grey though.
Hello, I have the same grinder. have disassembled most of the parts for cleaning but I cannot figure out how to separate the motor from the spindle slide block. Can you let me know the to are attached to each other? I have removed the height block from the bottom already so now. Does the spindle slide out with the motor? TIA
I wish I could tell you, but I did not need to rebuild my spindle bearings and left well enough alone. Spindles can be fussy. Most spindles rely on compression to preload a set of front and rear bearings. So I'd look for a large nut behind the wheel taper. I'm not close to the machine at the moment but will look when I get home. Thanks for watching, hope it was useful.
@@i-squared I have been watching your videos trying to learn from your restoration. Would be great if you can share how to remove the spindle sliding block from the motor for rust cleaning. Thank you.
Another question. what is the lever right next to stop block for (in middle of saddle)?
@@noonenoone1206 As for the lever. That locks the Z axis (in/out) movement of the saddle for grinding on the center of round objects. Using a horizontally mounted cylindrical part, usually mounted in a rotary table, or "Spin-Dex", with its axis aligned with the machine's X axis. The part is positioned with its feature to be ground under the wheel and the Z axis locked, This is especially critical if grinding a gear tooth or spline.
As to your first question. I did find there is a locking ring just behind the wheel mount taper. You'll probably need to make a special offset spanner to grab the hole in its side and remove. I would expect a left hand thread. That should enable you to pull the entire bearing and mount assembly off of the motor shaft. You'll may need to fashion some sort of puller to push the shaft through the bearings. I would also suspect there's also something holding the motor frame on to the rear of the mount. I would check for LONG bolts through, or under, the rear bell of the motor. I couldn't easily get to the rear of my machine. Later this summer I have a reconfigure of the shop planned and will look then.
@@i-squared thanks for sharing more detail. Actually in this video at 2:20 you were showing the motor with the spindle assembly attached to it. From this, I take it that the motor assembly must have been removed or pushed through the sliding block from the back. I just could not figure out what's holding the spindle to the sliding block - even with the spiral lock ring removed I was unable to get spindle to move so I stopped. I just ordered a user manual for this machine, and will tackle this again in near future. I got it all back together for now. As for the lever, I see what you meant now but on my machine it does not lock the Z movement; I see where it's supposed to clamp of the rectangular bar under the saddle but it does not move that far to clamp the bar. Will tackle this later. Thanks much for your time. I learned a lot from watching your two videos on this surface grinder.
